[Magnetic resonance tomographic diagnosis of vascular processes in the vertebrobasilar system--analysis of 35 of our own cases and a literature review].

35 patients with abnormalities of the vertebrobasilar system were studied via magnetic resonance imaging (11 saccular aneurysms, 10 vascular malformations, 9 basilar arteries with dolichoectasia, 5 thromboses of the vertebral or basilar artery). The two smallest aneurysms of the basilar top had a diameter of 2-3 mm. Most vascular malformations could be differentiated by typical MRT symptoms.

[Follow-up and prognosis of herpes simplex encephalitis. Observations on 57 patients between 1960 and 1987].

A retrospective study of outcome in 57 herpes simplex encephalitis (HSE) patients treated between 1960 and 1987 is reported. HSE was confirmed by virus isolation or detection of intrathecal anti HSV synthesis. 24 patients did not receive antiviral therapy, 19 were vidarabine recipients and 14 were treated with acyclovir.

Uncoupling of hexose transport and phosphorylation in human gliomas demonstrated by PET.

Tumor uptake of [18F]2-fluoro-2-deoxy-glucose (FDG) was studied in 20 patients with histologically classified gliomas, using dynamic positron emission tomography (PET). Parametric images of local blood volume, glucose metabolic rate, transport and phosphorylation rate constants were generated by weighted non-linear least-squares fits on a pixel-by-pixel basis. Tumor metabolism, i.
